MACHINE FOR MIXING- MORTAR AND THE LIKE.

Specification of Letters Patent.

Patented Dec. 2%, 1915.

Application filed March 24, 1915. Serial No. 16,559.

To all whom it may concern:

Be it known that 1, PAUL F. REIMANN, a citizen of the United States, residing at 6426 Aberdeen street, in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Machines for Mixing Mortar and the like, of which the following is a specification.

My invention relates to mixing machines and particularly to machines of this class which are utilized principally to mix cement, mortar, concrete, and similar binding compositions for building purposes.

The objects of my invention are to provide a machine of the most simple construction in which the material is mixed as the machine is trundled or rolled along the ground and to so construct and arrange the same that the material may be easily poured in or dumped out. I accomplish these and other objects as fully set forth in the following specification and particularly pointed out in the appended claim, reference being had to the accompanying drawings in which embodiments of my invention are shown.

In the drawings, Figure 1 represents a side elevation of my improved mixing machine; Fig. 2 is a vertical central section my improved machine on line 22, Fig. 1, looking in the direction of the arrows in said figure; Fig. 3 is an enlarged detail fragmentary section illustrating one form of connection or joint between the two half portions or members of the drum or barrel of the machine; and Fig. 4 is an enlarged detail fragmentary section similar to Fig. 3 illustrating another form of connection or joint between the two half portions or members of the drum or barrel of the machine.

In referring to the embodiments or forms of my improved machine shown in the accompanying drawings in detail, like numerals indicate like or corresponding parts.

The barrel or drums of my improved mixing machine, I prefer to construct in separable parts so that it may be readily dismounted to expose the interior for cleansing or other purposes.

In the forms shown in the accompanying drawings, the barrel is in two half portions which are constructed in similar shape and size and are opposed to each other. Each of these portions comprise a circular body 1 andan endflange 2 which extends inwardly from the outer edge. Nhen the two portions are united, the bodies 1 together constitute the circular body of the barrel or drum, and the flanges 2 form the respective ends thereof as shown in Fig. 2. I prefer ably detachably secure the two portions together by bolts 3 or the like, which are fitted through openings in outwardly-extending annular flanges l-4 formed at the inner ends of the bodies 1, said flanges 4: being in close contact when the two portions are jointed or united to form an assembled barrel or drum as shown in Figs. 2, 8, and 4:.

To support the barrel or drum upon the ground, I preferably form or attach an annular band or ring to the periphery thereof. In the embodiments shown in Figs. 3 and 4, the band or ring is located so as to extend around the center of the circular body and concentric therewith and being connected to the outer peripheral edge of the inner flanges 4.

As shown in Fig. 3, the band or ring is in two parts 5-5, each of which is integrally connected to one of the flanges 4., being formed by bending the outer marginal portion of the flange outwardly so as to extend at a right angle thereto.

The band or ring illustrated in Fig. 4; is in one piece and is formed separately from the inner flanges le- L to which it is removably secured by screws 6. To distinguish this form of band or ring from the form shown in Fig. 3, it is indicated in Fig. 4 by the nu meral 7.

By referring to Figs. 1 and 2, it will be noted that the ends of the barrel or drum are each provided with a comparatively large central opening 8 through which the material is conveniently poured into the barrel or dumped out of said barrel. To facilitate the dumping, the outer flanges 2 are preferably made so that they extend downwardly and inwardly when the machine is turned to a dumping position or upon one of its ends. This will be clearly understood by referring to Fig. 2 in which the flanges 2 are shown extending inwardly toward the axis of the barrel or drum from the respective outer edges of the two half portions and at an angle greater than a right angle or an obtuse angle to the body. To prevent the material from merely sliding upon the interior of the barrel or drum and thus not thoroughly and intimately mixing, 1 preferably arrange a plurality of radial partitions or barriers 9 within the barrel or drum which are located at proper intervals and are attached to the interior 01 the circular bodies 1 and the flanges 2. In the embodiment of my invention shown, these barriers are each constructed in two halves which are respectively attached to the half portions of the barrel or drum and which when the barrel or drum is properly assembled register with each other and extend completely across the outer portion of the interior mixing chamber within the barrel or drum as shown in Fig. 2 and impede and interrupt the progress of the material as the barrel is rotated, and thereby produce a more thoroughly and complete mixing of the said material. Each of the two portions of each barrier 9 is preferably provided with an opening 10, as shown in Fig.

2, through which a portion of the material can flow when the machine is operatin A suitable handle is provided for trundling the barrel or drum along the ground and thereby operating the machine. As shown in Figs. 1 and 2, the handle comprises an outer handle bar 11 and two parallel arms 12-12 extending inwardly from the respective ends of said bar. The inner ends of the arms are enlarged as shown in Fig. l and are provided with openings through which the outer extremities of a spindle or axle 13, extending centrally through the barrel or drum, are fitted. The spindle or axle 18 is preferably supported from the barrel or drum by two spiders or plates,

each of which has a series of radial arms 14 by screws 15 or other suitable fastening means, and a central bearing 16 through which the spindle or axle passes. The spindle or axle 13 is preferably detachably fastened to the arms llll by pins 17 so that the entire machine can be quickly dismounted by re- Copies of this patent may be obtained for five cents each,

moving-the pins, detaching the arms of the handle, and removing the bolts 3.

The operation of this improved machine is very simple, the material being poured into the barrel or drum through the end openings, the operator takes hold of the handle and trundles it along the ground revolving the barrel or drum and mixing the material. In this way the material is mixed as it is carried to the desired point. To dump it, the machine is turned from its trundling position over upon one of its ends so that the material will run out of the end opening by gravity. The dumping operation is greatly facilitated by the slope or truncated conical form of the ends as previously described.

lVhile I have illustrated and described a preferred form of construction for carrying my invention into effect, this is capable of a wide range of variation, alteration, modification, and change without departing from the spirit of my invention. I, therefore, do not wish to be limited to the construction herein shown and described but desire to a ail myself of all such variations, alterations, modifications, and changes as fairly fall within the scope of the appended claim or may be construed to be within the scope thereof by invoking the doctrine of equivalents.

I claim as my invention:

A, mixer consisting of two sections having a flanged connection forming a barrel with a central tread ring, each of said sections having an inclined outer end portion with a central opening, and means connected with said sections for trundling the barrel.

In testimony whereof I have hereunto atfixed my name in the presence of two witnesses.
